I have a csv that has as delimiter SOH character does neo4j import tool support this character ? through load csv i succeded to with fieldterminator '.' in browser
Yes, it possible - you need use escape sequence of SOH character:
LOAD CSV FROM "file:///soh.csv" as row FIELDTERMINATOR "\u0001"
RETURN row
For command line:
String expression can be normal characters as well as for example:
'\t', '\123', and "TAB".
../bin/neo4j-import --into ./db/ --nodes soh.csv --delimiter "\0001"

I need to convert csv into postgres table. I using the query below:
copy public.itens_2019 from 'C:\itens.csv' delimiter ',' CSV HEADER;
108,62,'C','Falência de Empresários, Sociedades Empresáriais, Microempresas e Empresas de Pequeno Porte','A',,,,
it is possible to observe that the texts are enclosed in quotation marks, because the text has commas. This way I am not able to extract the columns correctly.
try with the below command
copy public.itens_2019 from 'C:\itens.csv' delimiter ',' CSV HEADER QUOTE '''';
You can try with below query for specific column.
copy table_name(column1,column2,column3,column4,column5) from 'C:\itens.csv' DELIMITERS ',' CSV;
I have a large body of text and other data that I need to import into Postgres. This text contains all the possible single-byte characters. This means I can't choose ",", ";", "-" or any other single-byte character as a delimiter in my CSV file because it would be confused by the text that contains it.
Is there any way to chose a multibyte character as a delimiter, use multiple characters as a delimiter or use COPY command in some other way to solve this?
Command I'm using:
COPY site_articles(id,url,title,content) FROM '/home/sites/site_articles.csv' DELIMITER '^' CSV;
This means I can't choose ",", ";", "-" or any other single-byte character as a delimiter in my CSV file because it would be confused by the text that contains it.
CSV has an escaping mechanism. Use it. Quote strings that contain the delimiter character ,, and if the quoted string contains the quote character, double the quote character.
e.g. if you want to represent two values Fred "wiggle" Smith and one, two, you'd do so as:
"Fred ""Wiggle"" Smith","one, two"
At time of writing (9.5) copy does not support multi-byte characters as delimiters. You can use 3rd party ETL tools like Pentaho Kettle, though.
I'm trying to import a CSV file into PostgreSQL but I am having an issue with special characters.
I'm using the following command
./psql -d data -U postgres -c "copy users from 'users.csv' delimiter E'\t' quote '~' csv"
It works fine until it encounters a field with the '~' which I'm using as a quote value to not break the existing quotes and inverted commas etc.
How do I escape this character in the csv file 'Person~name' so that it will import as 'Person~name'
CSV rules are listed in https://www.ietf.org/rfc/rfc4180.txt
To embed the quote character inside a string:
If double-quotes are used to enclose fields, then a double-quote
appearing inside a field must be escaped by preceding it with
another double quote. For example:
"aaa","b""bb","ccc"
In your case, replace double-quote by tilde, since you've choosen that delimiter.
Example:
test=> create table copytest(t text);
CREATE TABLE
test=> \copy copytest from stdin delimiter E'\t' quote '~' csv
Enter data to be copied followed by a newline.
End with a backslash and a period on a line by itself.
>> ~foo~~bar~
>> \.
test=> select * from copytest;
t
---------
foo~bar
I was trying to import a CSV file into a PostgreSQL table using the COPY command. The delimiter of the CSV file is comma (,). However, there's also a text field with a comma in the value. For example:
COPY schema.table from '/folder/foo.csv' delimiter ',' CSV header
Here's the content of the foo.csv file:
Name,Description,Age
John,Male\,Tall,30
How to distinguish between the literal comma and the delimiter?
Thanks for your help.
To have the \ to be recognized as a escape character it is necessary to use the text format
COPY schema.table from '/folder/foo.csv' delimiter ',' TEXT
But then it is also necessary to delete the first line as the HEADER option is only valid for the CSV format.
im am importing data to postgresql with this comand
COPY codigos_postales
(CPRO, CMUN, Nombre_Municipio, CP, Municipio_CP, Lugar_CP)
FROM 'path' WITH DELIMITER E'/t';
But i got this error.
ERROR: COPY delimiter must be a single-byte character
If you're trying to specify a tab as the delimiter, you want E'\t' (the escape character is a backslash not a forward slash) or just a literal tab ' '.
You can see that with:
regress=> SELECT E'\t' AS backslash, E'/t' AS forwardslash;
backslash | forwardslash
-----------+--------------
| /t
(1 row)
If the delimiter is actually the string /t then you won't be able to use COPY, as it only supports single character delimiters.
your delimiter looks like a little bit complex but not a single byte char... Try with '\t'.
